they deposit their load because otherwise it gets too heavy
It drops the material. This is called deposition :)
The heaviest sediment will always be deposited first. Which sediment is the heaviest in that flowage can vary widely.
A fan-shaped deposit at the mouth of a river is known as a delta. Deltas form when a river flows into a larger body of water, like a sea or ocean, and deposits sediment and other material it has carried downstream. Deltas are typically characterized by their flat, triangular shape.
Natural levees are formed when floodwaters deposit sediments along the banks of a river during periods of flooding. As the water slows and spreads, it drops its heaviest sediment load first, building up a mound of material that acts as a barrier against future flooding. Over time, these deposits create elevated ridges along the riverbanks that help to contain and control the flow of water.
This deposit is called a "delta".
The end of the river. Known as the mouth of the river.
a place where a river meets the shore
The river drops the heaviest material first.
accumulated sediments on the bottom of the river
A deposit at the opening of a river is called delta.
A deposit at the mouth of a river is called a delta. This land form is created because of the deposition of sediments carried by a river as the flow leaves its mouth.
the nile delta is a fan-shaped mud deposit at the mouth of the nile river
